Patented. June 21, 1921 Application filedlMarch 11, 1918; Serial No. 221,604;

ToaZZ whom ilk may concern 1 Be it known that I, GEORGE J. Sniss, a. citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Improvement in Mechanically-Actuated Horns, of which the following is a specification.

My invention relates to that part of the horn which forms a guide for the actuator, which actuates the diaphragm. In the horn, with which I am familiar, these guides are usually made of a number of pieces of sheet metal riveted together and are secured to the horn body by means of screws, rivets or solder.

Owing to the fact that horns of this type are very roughly handled by users, frequently mounted on trucks where they are operated by the foot with a violent kick instead of being pressed by the hand, the supporting means for securing the guide in place becomes dislodged, andthe horn becomes inoperative, frequently at the very time it is most needed.

My invention has for its object to provide a guide in which the means for securing it to the horn body will be formed integral with it, and which may be stamped from the single piece of sheet metal.

My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are a part of this specification, in which:

Figure 1 is a vertical sectional view of a horn equipped with my improved guide.

Fig. 2 is a detail view, showing a side elevation of the guide.

Fig. 3 is an enlarged fragmentary sectional view, showing the means for securing the guide to the horn body.

Fig. 4. is a cross section of the guide, taken on the line w-w in Fig. 2.

Similar reference numerals refer to similar parts throughout the entire description.

As shown in the drawings, the horn is provided with a cylindrical body 1, equipped with a diaphragm 2, in the center of which is mounted a lug 3, which is engaged by serrations 4, cast or formed upon the periphery of the disk 5, mounted upon a shaft 6, which is suitably journaled in bearings mounted in the side walls in the body 1. A pinion 7 is mounted upon the shaft and suitable clutch mechanism is provided to cause the pinion to engage. the disk and rotate it, when the pinion is. rotated-in the desired direction.

This rotation is accomplished through the medium of an actuator 8, which is preferably formed in accordance with the descript1on in my copending application Serial Number 221,601, although it will be apparent to persons skilled in the art that my improved guide can be'used with any of the actuators employed in the standard forms now on the market.

The actuator is reciprocated in my improved guide 10, which is rectangular in cross section, and has tongues 11 and 12, stamped out of its side adjacent one end thereof. These lugs are adapted to enter perforations 13 and 14, formed in the wall of the cylindrical body 1, when they are clenched on the inside as clearly seen in Fig. 3, serving to make a secure and rigid connection between the guide and the horn body, so that the metal itself will have to be fractured before the guide can become inoperative. Extensions shown in dotted lines in Fig. 2 are provided on the lower end of the guide, and are bent inwardly forming a shoulder against which the coil spring 15, which is of the usual construction, exerts its tension.

A segmental recess is stamped in the guide to permit the engagement of the teeth of the pinion 7 with the teeth formed upon the actuator.

It will be apparent from the foregoing description that changes may be made in the details of construction of the guide without departing from the scope of the invention, and I do not desire to be understood as limiting myself to the precise shape or details, as illustrated, which are furnished for the purpose of disclosing the preferred form or embodiment of my invention.

Having described my invention what I regard as new and desire to secure by Letters Patent of the United States, is:

1. In a signal, a body having apertures in alinement in its side wall and apertures in the wall at each side of one of the first mentioned apertures, a guide in the first mentioned apertures, tongues integral with the sides of the guide inserted in the second mentioned apertures from above and em bracing the body between the second mentioned apertures and the guide, the said body of the guide and the said tongues bearmentioned apertures from above and embracing the body between the second mentioned apertures and the guide, signal actuating means operating in the guide, a

"sounder movedby the actuating means, the

said body of the guide and vthe said tongues bearing against the upper surface. of. the

body whereby the body sustains'the'strain due to operation, and 'inturned portions of the guide which close one end thereof.

In testimony whereof, I have signed "the foregoing specification.

GEORGE JrsEIss.
